Unlike with China, Russia or Cuba, countries where the U.S. has relatively few tools to force Edward Snowden's handover, the Obama administration could swiftly hit Ecuador in the pocketbook by denying reduced tariffs on cut flowers, artichokes and broccoli if it grants Snowden's request for asylum. Those represent hundreds of millions of dollars in annual exports for this country where nearly half of foreign trade depends on the U.S. (AP Photo/Dolores Ochoa)
